Option A Mobile Technology

SLAM Scanning

Walk-and-scan mobile capture with no per-station setup

SLAM (Simultaneous Localization and Mapping) scanning uses continuous motion capture for rapid area documentation. Walk-through systems like the NavVis VLX 3 capture continuously at walking pace, so coverage is limited by the route rather than by the number of tripod set-ups; the rate achieved depends on layout and the density required.

Pros

Continuous data collection — no per-station setup
Large-area coverage without repositioning a tripod
No tripod setup per station
Natural walk-through workflow
Handles stairs and multi-level
5mm local accuracy (1 sigma, NavVis 500 m² test environment)

Cons

Lower accuracy than static (5-20mm vs 1-2mm)
SLAM drift on long routes without loop closure
Lower point density than static
Not suitable for flatness testing
Repetitive features can cause tracking issues

Best For

Large facilitiesQuick as-built documentationMulti-story buildingsTime-critical projects

Option B Tripod-Based Technology

Static Scanning

Station-based scanning for 1-2mm survey-grade accuracy

Static (tripod) scanning uses fixed scanner positions for maximum accuracy and point density. Systems like the Trimble X12 achieve millimeter-level accuracy (3D point accuracy 2.2 mm @ 20 m)—essential for floor flatness, bolt location documentation, and contractually defensible survey work.

Pros

Survey-grade accuracy (1-2mm)
Highest point density
Contractually defensible measurements
Floor flatness testing capability
Bolt-by-bolt location documentation
Best for engineering deliverables

Cons

Slower capture (tripod setup each position)
More scan positions required
Tripod access limitations
More expensive per sq ft for large areas
Multi-story requires separate setups per floor

Best For

Our Expert Verdict

Depends on Your Needs

SLAM covers large areas continuously at walking pace with 5-20mm accuracy. Static achieves 1-2mm survey-grade accuracy required for engineering work. A 2024 study found "comparable accuracy" between methods, though static remains essential for flatness testing and bolt locations.

Choose SLAM Scanning if...

Choose SLAM (NavVis VLX 3, BLK2GO) when speed matters and millimetre-class local accuracy is acceptable: large facilities, as-built documentation, time-critical projects.

Choose Static Scanning if...

Choose Static (Trimble X12, RTC360) when millimeter-level accuracy is required: floor flatness, engineering measurements, legal documentation, bolt locations.

Frequently Asked Questions

Can SLAM replace static scanning?

For many applications, yes. A 2024 research study found "comparable accuracy of static and new-generation SLAM scanners" with 20mm RMSD in 120m tunnels. However, flatness testing and bolt-by-bolt documentation still require static scanning.

How fast is SLAM vs static?

The NavVis VLX 3 captures continuously while the operator walks, so there is no set-up time per station; a tripod scanner has to be positioned, levelled and scanned at every station. Neither NavVis nor the tripod manufacturers publish an area-per-hour figure — the rate achieved depends on layout, obstructions and the point density required.

What accuracy can SLAM achieve?

NavVis publishes 5mm local accuracy (1 sigma) for the VLX 3, measured in its own 500 m² test environment. NavVis notes that absolute accuracy depends on the size of the environment and can be controlled with control points, but publishes no figure for the result with control points. Typical field accuracy for SLAM systems generally is 10-20mm.

When is static scanning mandatory?

Static is required when measuring floor flatness, documenting exact bolt locations, creating contractually defensible surveys, or when specifications require 1-2mm accuracy.

Which does THE FUTURE 3D use?

We use both methods strategically: NavVis VLX 3 SLAM for large facilities and rapid documentation; Trimble X12 and Leica RTC360 static scanning for survey-grade engineering projects requiring millimeter accuracy.
